Abstract (en)
[origin: WO9602580A1] Catalysts for the polymerization of olefins are disclosed, which comprise the reaction product of: (A) a bridged and/or substituted cyclopentadienyl compound of titanium, zirconium or hafnium; (B) an organometallic aluminum compound of the formula (II) Al(CH2-CR<4>R<5>R<6>)wR<7>yHz, wherein in the (CH2-CR<4>R<5>R<6>) groups, which are the same or different, R<4> is an alkyl, alkenyl or arylalkyl group having from 1 to 10 carbon atoms, R<5> is an alkyl, alkenyl, aryl, arylalkyl or alkylaryl group having from 3 to 50 carbon atoms which is different from a straight alkyl or alkenyl group and, optionally, R<4> and R<5> fused together can form a ring having from 4 to 6 carbon atoms, R<6> is hydrogen or an alkyl, alkenyl or arylalkyl group having from 1 to 10 carbon atoms, the R<7> substituents, same or different, are alkyl, alkenyl, aryl, arylalkyl or alkylaryl radicals containing from 1 to 10 carbon atoms and, optionally, can contain Si or Ge atoms, w is 1, 2 or 3, z is 0 or 1, y = 3-w-z; and (C) water. The molar ratio aluminum/water is comprised between 1:1 and 100:1. These catalysts show an improved activity with respect to known catalysts wherein an aluminum compound different from those of the above formula is used.
